New GUI features

synccovers path processing

Allow trailing path separator

xml processing

1. Removed non-standard complaint pretty printing of generated xhtml files, use lxml pretty print instead
2. On multiple requests replaced 8211 with 8212 in spaces.xsl
3. Used latest pillow and lxml modules

Notes titles - again

Do real formatting for notes body title (if any)

href processing

1. Attempt to process "href" attributes with wrong namespaces (happens quite often)
2. Improved and cleaned error diagnostic

More images

Completely re-done image parsing and processing. fb2mobi now relies on Pillow's ability to recognize image format and provide proper mime type and file extension. Accordingly program now properly warns if format is not supported by Kindle or at all.

Images

In case when image links in the body did not specify image with extension cover generation was failing and removal of ".png" transparency did not do anything.

Features

1. When generating "floating" notes - keep original title if available
2. When processing author and book title formats allow escaped curly brackets \{ and \}
3. Compensate for bug in cssutil - allow "rem" units to be used without reporting errors
4. Properly process main body without "title" - use book author and book title instead to keep resulting book and ncx toc structures intact.

Maintenance

Python 3.6.1 - all platforms and up to date packages
